SPECIFICATION forming part of Letters Patent No. 298,905, dated May 20, 1884. Application filed November 26, 1883. (No model.)

T0 [6 whom it may concern.-

Be it known that I, WILLIAM STEWART SMITH, of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Brick-Machines, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1, Sheet 1, is a plan view of my improved brick-machine. Fig. 2, Sheet 2, is a rear elevation of the same, partly in section, and parts being broken away. Fig. 3, Sheet 2, is a front elevation of the same, parts being broken away. Fig. 4, Sheet 3, is a sectional side elevation of the same, parts being broken away. Fig. 5, Sheet 3, is a face view" of the cam giving motion to the wheel-driving pawl.

The object of this invention is to facilitate the manufacture of pressed bricks, and also to simplify the construction of brick-machines.

The invention consists in a brick-machine constructed with a wheel provided with moldopenings, a cam-driven pawl for revolvingthe mold-wheel intermittently, and a series of plungers worked by cam-driven levers, whereby the mold-openings will be filled with clay, the clay pressed into bricks, and the pressed bricks discharged from the wheel automatically. The mold-wheel is locked in place by alatch operated by a pin attached to a plunger, and engaging with recesses in the rim of the said wheel when the said plunger is moving forward and released by the rearward movement of the said plunger. Adhering clay is removed from the faces of the mold-wheel and the press ing plungers by scrapers sliding upon guiderods attached to the machine-frame, the said scrapers being connected by rods with aleverpawl, which engages with recesses in the rim of the mold-wheel, is tripped by a rod attached to the machine-frame, and drawn back by a suspended weight, so that the said scrapers will be operated by the movement of the said mold-wheel, as will be hereinafter fully described.

A represents the base of the machine.

To the base A are attached supports 13, in bearings at the tops of which revolves a shaft, i

To one end of the shaft 0 are attached a fast pulley, D, and a loose pulley, E, to receive a driving-belt, to which motion may be given from any convenientpower. To the other end of the shaft 0 is attached a miter-wheel, F, the teeth of which mesh into the teeth of a miterwheel G, attached to the end of the shaft H. The shaft H revolyes in bearings at the tops of supports I, attached to the base A. To the other end of the shaft H is attached an eccentric, J, in the face of which is formed a camgroove, K, to receive the projecting end of a pin, L, attached to a plate, M, so that the said plate will be moved up and down by the revolution of the cam J K. The plate M slides up and down upon the side of the vertical plate N, attached to the upright frame 0 of the machine. The outer end of the slide M is bent to one side at right angles, crosses and slides upon the outer edge of the plate N, and has an eye formed in it to receive a guide-rod, P, the lower end of which is attached to the base A. The guiderod 1? is parallel with and at a little distance from the vertical outer edge of the plate N, and its upper end is bent inward at right angles, and is attached to the upper edge of the said plate N. The plate M has a horizontal slot, M, formed through it to receive the bolt Q,

which passes through a slot, N, in the plate N, and has a pawl, R, pivoted to its other end, to engage with recesses S, formed in the adjacent side part of the face of the rim of the mold-wheel S, the said recesses S being so formed that the said pawl in its downward movement will engage with the said recesses and turn the said wheel forward. The slot N is curved upon the arc of the rim of the wheel S, so that the pawl R as it moves downward will remain in contact with the said rim. The middle part of the rim of the mold-wheel S is made V-shaped and rests upon grooved rollers T, pivoted to supports U, attached to the base A, or to the lower part of the upright frame 0. In the wheel S is formed a circular row of openings, S each of therequired shape and size of the bricks, and which serve as molds for the bricks, the wheel S being made of such a thickness that each mold-opening S will contain the desired amount of clay to be pressed into a brick. The frame 0 supports the mold-wheel S in a vertical position, and is made of such a width that the whole of each mold-opening S will be exposed at each side of the said frame.

To the side of the frame at the front of the exposed part of the wheel S, that is moving upward, is secured a hopper, V, to receive the clay, and from which the clay is pushed into the mold-openings S of the wheel S, as the said openings successively come opposite the discharge-openings of the said hopper V, by the follower W, which works through an opening in the lower part of the front of the said hopper V. The clay is kept from being pushed through the mold openings S by a plate, X, attached to the frame 0 in the rear of the projecting part of the wheel S and directly opposite the hopper V.

To the outer end of the follower W is pivoted the end of a lever, Y, which is fulcrumed at its middle part to an arm of an angular bar, Z. The ends of the angular bar Z are bent upward, and are secured to the forward end posts of the frame 0. Several holes are formed in the angular bar Z and in the lever Y, so that by moving the fulcrum-pin a from one to another of the said holes the said lever can be adjusted to give a longer or shorter movement to the follower W, as the character of the clay may require. The inner end of the lever Y is pivoted to the outer end of a bar, b, attached to the forward end of the bar 0, which slides in ways in the frame 0, and passes through the circular central opening through the wheel S.

To the rear end of the sliding bar 0 is pivoted the inner end of the bar (I, the outer end of whichis pivoted to the lever e. The upper end of thelever eis pivoted to a support attached to the rear upper part of the frame 0. The levere is pivoted at its lower end to the inwardly-pro- 0 jecting upper part of the lever f by the pivot g.

Thelower end of thelever f is pivoted to asupport attached to the base A of the machine. The lower end of the lever c is slotted to receive the pivot 9, so that the two levers e f will operate as a toggle-joint. The lever f is slotted to receive the lower end of the lever e and the cam h, which rests against a pin, 6, attached to the parts of the lever f near the pivot g. The' friction between the cam 71. and the pin 6 is lessened by a tubular washer or roller placed upon the said pin. One part of the lever f projects above the other, and to thesaid projecting end is attached a pin, 9', which, as the levers e f complete their forward movement, enters a cam-groove, 70, formed in the side of the cam h, as shown in Fig. 4, so as to draw the levers e f back quickly. The cam 71. is attached to the shaft 0.

To an upward projection on the upper side of the rear part of the sliding bar 0 is rigidly attached the lower side of the rear part of the plunger Z, the inner part of which projects from its support to such a distance that it can pass into a mold-opening, S in the 65 wheel S to a sufficient depth to compress the clay into a brick between the said plunger 1 and a similar plunger, 9n, entering the said opening from the other side of the wheel S. The plunger m slides in ways in the upper forward part of the frame 0, and to its slotted outer end is pivoted the upper end of a short lever, n, which is pivoted at its middle part to the frame 0. The lower end of the lever a and the upper'end of the lever 0 are pivoted by the same pin or bolt in the slotted outer end of the sliding bar 0, so that both the levers n 0 will be operated by the movements of the said sliding bar. The lower end of thelever 0 is pivoted to the outer end of the plunger 12, which, when pushed inward, 8o enters the mold-opening S at the lowest part of the wheel S, and forces the pressed brick out of the said opening to the platform-q, whence it is removed by the off-bearers. By this arrangement a brick will be pressed at the upper part of the wheel S, and a pressed brick will be discharged from the lower part of the said wheel at the same time. The wheel S is locked in position for the plungers Z m p to enter the proper mold-openings S by 0 a latch, r, pivoted to the frame 0, or to supports attached to the said frame, in such aposition that its forward end, when lowered, will enter a recess, S in the side part of the rim of the wheel S, as shown in- Figs. 2 and 4. 5

The forward end of the latch r is forced downward to enter a'recess, S, of the wheel S by a pin, 8, attached to the plunger m, and which strikes against the inclined or rounded lower side of the middle part of the latch r, as shown in Fig. 4. As the plunger m is drawn back the outer end of the latch 1" drops, raising the forward end of the said latch out of the recess. S and allowing the wheel S to be turned to bring the next mold-opening S opposite the plungers l m by the action of the pawl R, as hereinbefore described.

To the frame 0, at each side of the wheel S, and above and below the inner ends of the plungers l m, are attached two rods, 25, which pass through, and upon which slide the upper and lower ends ofv the scrapers To the center of the scrapers u are pivoted the inner ends of two rods, v, the outer ends of which are pivoted to and connected by a cross-rod, w.

To the cross-rod w is pivoted a lever-pawl, x, the engaging end of which is held against the side part of the rim of the wheel S, so as to engage with recesses S*, formed in the said rim, by a spring, y, attached to the cross-rod w, and which presses against the said leverpawl 00. As the part of the wheel S with which the lever-pawl x is engaged moves upward, the said pawl, by the connecting-rods 1), moves the scrapers u forward on the guiderods t between the adjacent faces of the wheel S and v the plungers Z m, to remove therefrom the adhering clay until the projecting arm of the said lever-pawl strikes against a staple or 130 other trip-rod, 2, attached to the frame 0, and which withdraws the engaging end of the said lever-pawl from the recess S* of the said wheel S. As the lever-pawl x is disengaged from the wheel S, the said lever-pawl is drawn downward intoposition to again engage with the said wheel by a weight, 1, attached to the lower end of the cord or chain 2, the upper end of which isattached to an outwardly-proj ecting arm, 3, formed upon or rigidly attached to the cross-rod w. The disengagement of the pawl 50 by the trip-rod 2 permits the weight 1 to carry the scrapers a back to their first position at one side of the plungers, which can then enter the 1n old-openings to press the brick.

In using the machine, as each mold-opening S of the wheelS comes opposite the discharge-opening of the hopper V, it receives the proper amount of clay by the forward movement of the follower W, and as each filled mold-opening S comes opposite the plungers Z m the wheel S is locked in position by the latch r, and the clay is pressed into a brick by the inward movement of the said plungers Z m, and at the same time a pressed brick is forced out of the lowest mold-opening, S, by the inward movement of the plunger 1), so that each time the wheel S is moved through the space of one mold-opening S a mold-opening will be filled with clay, a brick will be pressed in a second mold opening, and a pressed brick will be discharged from a third mold-opening, so that the operation of themachine will be continuous.
